v0.4.3

0.4.3

Improved

• Reworked the public docs so the README and benchmark notes tell a clearer first-run story: the product value, benchmark caveats, and command guidance are easier to scan without losing detail.
• Hardened setup diagnostics so sift doctor now treats obvious placeholder API keys as incomplete configuration instead of reporting a false healthy state.
• Hardened config template writes so sift config init uses the same secure file-permission posture as the guided config writer.

Added

• Added a lightweight CONTRIBUTING.md for first-time contributors.
• Added simple GitHub issue forms for bug reports and feature requests, plus a security contact link for private vulnerability reporting.
• Added regression tests covering placeholder API-key detection in doctor and secure template-config writes.

Changed

• Updated the security policy to reflect the current supported version line and point reporters to GitHub's private advisory flow.
• Bumped package version to 0.4.3.
